Self-contained electronic telephone ring recorder and method for eliminating errors

ABSTRACT

A pocket calculator-sized, voice controlled, self-contained electronic telephone ring recorder contains a casing with a liquid crystal display, a voice control system, a decoder, and microprocessors. A number of rings transmitted to the telephone ring recorder is translated into digits shown on the liquid crystal display. The digits identify callers and reasons for calling. A linear digital watch attached to the casing allows to determine the time of a call.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates to a telephone call recorder using the voice control technique and transforming successive sounds in digits displayed on a screen.

SUMMARY OF THE INVENTION

1. Purposes of the Invention

It is an object of the present invention to provide a telephone call recorder using the voice control technique and transforming successive sounds in digits displayed on a screen which can be grouped in order to read easily.

These and other objects and advantages of the present invention will become evident from the description.

The novel features which are considered as characteristic for the invention are set forth in the appended claims. The invention itself, however, both as to its construction and its method of operation, together with additional objects and advantages thereof, will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

In the accompanying drawings, in which are shown several of the various possible embodiments of the present invention:

FIG. 1 is a perspective view of a telephone call recorder; and

FIG. 2 is a schematic view of a watch.

DESCRIPTION OF INVENTION AND PREFERRED EMBODIMENT

This recorder, the size of a pocket calculator, allows, starting from the telephone ringing, the registration on a liquid crystal display (1) of predetermined coded messages. The liquid crystal display is divided into segments. It is independent of any source and it is supplied by a battery which gives an autonomy of one year. A single glimpse on the display allows to understand all messages. It is completely visual which allows the utilization of the telephone by millions of deaf-mutes in the world. It includes a protection shutter (2) with an opening on the micro with vocal control (3). This shutter has a location in which one slides a cardboard sheet (5) with the names of all the members of the family group and friends as well as the code numbers attributed to each (6). Each ringing acts by the intermediate of the microphone (4) on the microprocessor, the decoder, the set-up system of the simple intervals between the units, the dozens and the hundreds and of change of state for the subsequent message. The sensibility of the micro is controlled by a potentiometer (7). In order to avoid the inherent errors of the systems in force in all the telecommunications of the world, not all the subsequent ringings are translated into corresponding digits but the ringing couples. One uses to form the code numbers the odd digits 1, 3 and 5. To transmit the signature 31 one does two calls, at the first one allows it to ring three times, at the second once. If on the other end of the wire the recorder has received four ringings and then two, it will record at least 31. The set-up of a simple interval is done after four seconds of silence, a time longer than silence between two successive ringings, a change of state occurs, after twenty seconds of silence. A number of ringings higher than six is translated by means of a zero.

In order to indicate the timetable of the calls of the last eighty-four hours a linear digital watch is connected to the electronic system. The time is indicated by a digital cursor which moves along the dial of eighty-four hours. This one allows a visible twenty hours track from the first ringing of a message (8). There are as many timetables as registered messages. The reading of the messages of the figure informs us that eleven calls have been received, the seventh the 311 registered at 10.30 comes from 31, Alice, who asks to be called back urgently. All double digits at the end of a message have this meaning. The dialling code 1, (10) first registration day, is replaced with 2 at midnight, and at the same time an asterisk appears * meaning the end of the messages of the day. At saturation of the display, the registered calls on the first line are erased, to leave place for the present ones and so on. This recorder is not in competition with existing and future recorders, it is near, it is furthermore a useful gadget.

With the help of its small size, its full autonomy, its great reliability and its aestheticism because it has two surfaces to show, it can become the inseparable companion of each telephone. Its relatively low purchase price, its free use favours its expansion to all the rich and poor countries.

The adding of a light synchronized with ringings to the telephone allows finally the deaf-mutes to utilizes the telephone.

It will be understood that each of the elements described above, or two or more together, may also find a useful application in other types of recorder differing from the types described above.

While the invention has been illustrated and described as embodied in the context of a telephone call recorder using the voice control technique, it is not intended to be limited to the details shown, since various modifications and structural changes may be made without departing in any way from the spirit of the present invention.

Without further analysis, the foregoing will so fully reveal the gist of the present invention that others can, by applying current knowledge, readily adapt it for various applications without omitting features that, from the standpoint of prior art, fairly constitute essential characteristics of the generic or specific aspects of this invention.
